Description

The Jindal Ultra-Low Temperature Deep Freezer (-20°C to -40°C), model SMI-165ULDF-777, is equipped with a high-quality refrigeration system for rapid cooling. Its high-precision temperature control system simultaneously displays various parameters, including power voltage, internal cabinet temperature, and environmental temperature, clearly indicating the operational status. The temperature inside the cabinet can be set freely within the range of -20°C to -40°C.

The two-layer, heat-insulated foamed door with an airbag-type outer steel design effectively prevents the loss of refrigerating capacity.

High-efficiency Refrigeration System

  • The Freon-free refrigerant, compressor from an internationally renowned brand, and EBM fan ensure rapid cooling while being energy-efficient and environmentally friendly.
  • The refrigerating circuit, designed with proprietary intellectual property rights, guarantees high efficiency and stability.
  • The cabinet are made from high-performance insulation material, improving thermal insulation performance to a large extent.

Temperature Control

The high-precision microcomputer temperature control system, combined with platinum resistor temperature sensors, ensures exceptionally accurate temperature regulation.

Ergonomic Design

The high-quality steel plate structure with a phosphate coating, along with a galvanized steel sheet (or optional stainless steel) liner and a low-noise design, helps create a more comfortable environment.

Features

  • The digital temperature display shows various parameters simultaneously, such as the internal cabinet temperature, power voltage, and environmental temperature, clearly indicating the operating status.
  • The high-precision microcomputer temperature control system, combined with platinum resistor temperature sensors, enables users to set the internal cabinet temperature within a range of -20℃ to -40℃.
  • The compressor, supplied by a renowned international brand, and the EBM fan are powerful, energy-efficient, and highly effective.
  • The large-area finned condenser features a fin spacing of 2mm or less, providing a large surface area for heat dissipation and ensuring satisfactory performance.
  • The two-layer heat-insulating foamed door with an airbag-type outer seal, along with the multi-patented insulation design of the outer door system, effectively prevents refrigerating capacity loss.
  • The six sides of the cabinet are made from high-performance vacuum insulation material, significantly enhancing thermal insulation performance.
  • The well-developed alarm system includes multiple functions: high/low temperature alarm, door ajar alarm, power failure alarm, abnormal voltage alarm, sensor failure alarm, low battery alarm, poor condenser heat dissipation alarm, system failure alarm, and more.
  • The turn-on delay and stopping interval protection functions enhance reliability during operation.
  • The keyboard lock and password protection functions prevent unauthorized adjustments to operating parameters.
  • The rotating handle facilitates easy door opening.
  • The adjustable layered structure provides convenient storage for various items.
  • The liner, made from galvanized steel sheet (or optional stainless steel 304) suitable for medical use, is low-temperature tolerant, corrosion-resistant, durable, and easy to clean.

Scope of Application

Suitable for use in scientific research, cryogenic testing of special materials, low temperature resistance testing of biological materials, vaccines, biological products, military products, and more. It is ideal for research institutions, the electronics industry, the chemical industry, hospitals, health and disease prevention systems, university laboratories, military enterprises, and other similar applications.
